SEMIAUTOMATIC SEGMENTATION METHOD FOR ESTIMATING THREE-DIMENSIONAL VOLUMES

摘要

The invention concerns a method for estimating and segmenting the volume of a three-dimensional object in medical imaging, consisting in defining a given number of base points constituting a first three-dimensional form defined by facets; each facet of the first form being defined by three segments, the segments are divided by defining second order points adapted to the object outline so as to constitute a second three-dimensional form closer to the object outline than the first form; each segment is iteratively divided into sub-segments by defining third order points adapted to the object outline so as to constitute a third three-dimensional form closer to the object outline than the second form; the volume of the third form is then computed.
